Hydronephrosis

Article DOI 10.3389/fped.2020.00001
ObjectiveTo predict SFU grade of hydronephrosis
AI ApproachCNN; Layer-wise propagation to visualize output.
Data Source(s)Institutional series (2420 sagittal hydronephrosis ultrasound images)
Model Input256 x 256 pixel images of sagittal ultrasound
Model OutcomeSFU 0-4
Mild vs. Severe hydronephrosis
SFU 2 vs. SFU 3
Model MetricsSFU 0-4: F1 = 0.49, accuracy = 51%
Mild vs. Severe hydronephrosis: F1 = 0.78, accuracy = 78%
SFU 2 vs. SFU 3: F1 = 0.71, accuracy = 71%
Model UsabilityNA
AI = Artificial Intelligence, AUROC = Area-under-the-receiver-operator-characteristic, SFU = Society of Fetal Urology, CNN = Convolutional Neural Network
